Greetings all. New to this forum, but a veteran of Jaguar Forums. Yes, I visit those forums more often, as you might imagine.

Ok, here’s the story...’08 E350
Common issue with V6 intake manifold, code p2006. Determined cause as broken pivot lever.
Removed manifold, installed replacement pivot lever and related flap attachments. Reinstalled manifold. So far so good.
Start the car, still idling roughly. Take it for a short spin around the neighborhood. Running like crap, worse than before.
Read codes, and am now getting entire left bank cylinder misfire codes (0304, 0305, 0306). But, the p2006 is gone.
By the way, I did NOT remove the fuel rail when I took out the intake manifold
Go back and check that all fuel injector connectors and coil packs are connected on that bank...they are.
Cleared the misfire codes. Try to start car and I get crank but no start. Read codes and I get “0 dtc”. ?

Any helpful suggestions from those that have encountered this or similar?

Many thanks,
Windwhipped

Replace the intake manifold. There's a reason why the rods in front are made of plastic, they act as mechanical fuse.

Means your intake runners are jammed. From there you have very real possibility of the runners breaking and entering the engine, destroying it.

Seen it a few time.... Just get a new manifold and install.

Knightrider, thanks for the reply. The link you graciously provided regarding the p2006 code refers ONLY to Bank 1 (cylinders 1,2,3 on right side of engine), seems like the internal flaps are the culprit. Those flaps are controlled by their own actuator arm, correct? So, why am I getting misfire codes for all 3 cylinders (4,5,6 on left side of engine) on Bank 2? Seems like I'm missing something.

Because the intake runners control the amount of air getting into each bank. When one is jammed, there's less air getting into one side than other, hence the misfire.

Deplore, thanks. Always felt that would be the ultimate solution, just trying to understand the issue. The triumph of hope over reality is that there can be a simpler solution. Spend most of my time under the hood of my '00 XK8, first time delving into a Mercedes for a serious issue...

Dont listen to these people!! they are wasting your money for no reason!! The issue is nothing serious like they made it out to be!!! When you reinstalled the manifold, the gaskets were misplaced/out of placed, or even folded (even thought It seem to be perfect)!! .. which cause vacuum leaked!! It was a very common problem for people who replace the manifold themselves with the M272 engines. To be honestly, it is quite difficult to keep the manifold gaskets in place when reinstall the manifold. Some used fish string, I used super glue to hold the gaskets!! I took me 3 tried to get it right!!! You will have to reopen, reseat the gaskets, even replace if they were fold.... then everything will be back to normal.

You are probably both right. However the long term fix is to replace the manifold. I think it's around $672 for a new one from fcpeuro and a rebuilt one on eBay is about $350. Just depends if you want a lifetime warranty from fcp or just a one year warranty on the rebuilt one. Basically boils down to how long you want to keep the car. If you just want to drive it for a year or two, then if it's just a gasket problem then you're probably fine for that period, but as others said, eventually the flaps fall apart and grenades your engine. There's several youtube videos about how to do the gaskets and making sure they don't move.

I used a dab of super glue on the notches where the gasket is pressed in to hold it in place and it worked great.

FWIW, the plastic runners break due to oil ingestion from the evaporation system. If you have any oil in your throttle body, you need to replace the passenger cam oil separator & the housing right away.
